ALLEN c. BRANTINGHAM,

To allwhom it may concern:

Be it known that I, ALLEN C. BRANTI'nG- HAM, a citizen of the United States, residing at Toledo, Lucas county, Ohio,'have in vented a new and useful Automatic Heater,

of which the following is a specification.

This invention relates to treating material and especially caring for a stream of material in such a way that the device is not left charged with or containing the material to be treated.

This invention has utility when embodied as a heater for grain as in the preparation of wheat for milling.

Referring to the drawings: Figure 1 is a side elevation with parts broken away of an embodiment of the invention in a grain heater; Fig. 2 is a fragmentary detail view showing a different position of the driving means for the tilting hopper than the show: ing in Fig. 1, the former showing the hopper in closed or check position, while the latter shows the hopper in tilted or spill 1 position as would occur at one of the points in driving; Fig. 3 isa plan view with parts broken away showing features of the heater and controlling means therefor; Fig. 4 is a section on the line IV-IV, Fig. 1, looking in the direction of the arrow; and Fig. 5 is a View of the automatic dump with the check means rendered inoperative instead of in the position shown in Fig. 1.

The heater 1 is provided with a plurality of vertically disposed ways 2 having agitating or bafiie chains 3 therein. The stream of material coming to the treating device or heater 1 is received in the hopper 4 which has the plurality of openings 5 disposed to register with the ways 2. The material flowing from the hopper 4 through the openings 5 into the ways 2 is treated by being heated therein. The heating medium, as steam, may be supplied through the intake valve 6, the condensation passing out by the valve 7. The receiving hopper 4 is carried by rods 8 yieldably maintaining the hopper 4 in position through the springs 9. As this hopper 4 settles when loaded, it moves the slatted platform 10 farther away from the lower ends of the tubes or ways 2. The tubes or ways 2 have therebelow the funnels 11 discharging into the movable hoppers 12 normally hanging to be obstructed by the slats 13 between the slots 14 in the platform 10. These pivotally mounted or Specification of Letters'Patent.

Application filed October 13, 1913. Serial No. 794,823.

tiltinghoppers 12' have centralpins 15 engaging the notches 16 in a bar 17 carried by links 18 so that reciprocation of this bar 17 will'simultaneously rock the full set of hoppers 12. Continuous driving means is provided through the pulley 19 onthe shaft 20 which has the cam 21 against which cam 21 contacts the roller 22 carried by the bar 17. As the shaft 20 is rotatedto bring the short radius portion'23 of the cam 21mm contact ing relation with the roller 22, the spring 24 pulls the hoppers 12 into an emptying positionover the slots 14 as shown in Fig. 2. The longer radius portion 25 of the cam 21 is effective when contacting the roller 22" to tilt the hoppers'12 into a spill or empty.- ingposition at the other extreme from the showing in Fig. 2. The medial position of tliehoppers as shown in Fig. 1 is a check position for the material stream. l

The spring 24 abuts the slide 26 carrying the upright 27 connected by toggle links 28' to bespaced from the fixed bracket 29. This toggle 28 when in thestraight position as shown in Figs. 1 and 2 permits the continuous driving device to tilt the hoppers 12 toand fro over the check means or platform 10. In normal operation the spill of ma terial from the screen through the slots 14 is at such a rate that the auxiliary hopper 30 may not discharge sufliciently rapidly through this opening 31 to'keeppace with i the supply therethrough and this hopper 30 accordingly overflows into the main surrounding hopper 32 having its discharge opening 33. As the material stream lessens, this continuously leakable auxiliary hopper 30 of the automaticdump would tend to catch up and empty itself and accordingly this hopper 30, carried by thebrackets 34, link 35 and lever 36, tends not to overcome the adjusted flow position as permitted by the compression spring 37 and this spring 37 acts to pull down the link 38 as the hopper 30 in emptying rises, thus breaking the toggle 28 or tilting it down to the position shown in Fig. 5 thereby drawing in the slide 26 and forcing the bar 17 tocarry the roller 22 away from the cam 21, say to the overheated for should the stop not be with the heaters 12 in a tilted position, the immediate check upon material flow would result in the auxiliary hopper 3 breaking the toggle 28 at once efiectively discontinuing the driving means by tilting the hoppers t a position shown in Fig. 5. I

When the mill is started up 'no attention is needed for as the material is fed down to the hopper 30, it becomes weighted down and will automatically throw the links 28 into position to render the driving device effective in its control of the intermittent check means for the heater, thereby insuring at all times the most efficient results.

What is claimed and it is desired to secure by Letters Patent is:

' the heating capacity rate of the heater.

2. A grain heater embodying a way, way

intercepting mechanism, driving means for the mechanism, and an automatic dump for the heater including a member movable to disconnect the driving means from the mechanism.

3. A heater embodying a way for a stream of material, way intercepting mechanism and a dump device connected to the mechanism for emptying the heater upon cessation of material stream. I

A. A treating device embodying a way for a stream of material, way intercepting mechanism, emergency emptying means for the device connected to the mechanism operable by the stream.

5. A treating device embodying a Way for a stream of material, Way intercepting mechanism, material stream receiving emptying means for the device connected to the mechanism and controllable by the stream.

6. A treating device .embodying a plurality of parallel ways for streams of materials, intermittent check means for the material streams of said ways, and automatic disconnecting means rendering the check means inoperative.

7. A treating device for a stream of ma terial embodying intermittent check means for the material stream, and automatic setting means rendering the check means operative.

8. A treating device for a stream of material embodying intermittent check means for the material stream, and stream control means for controlling the check means.

9. A treating device for a stream of material embodying a tilting hopper, driving means for tilting the hopper, and an auxil iary hopper in the stream to connect and disconnect the tilting hopper and the driving means for said tilting hopper.

10. A device for treating a stream of material embodying a Way, relatively movable driving means for directing the material stream, stream intercepting means, and a stream weighted member connected to vary the position of the intercepting means as to the driving means.

11. A grain heater embodying a way for a stream of material, relatively movable driving means for directing the material stream, stream intercepting means, and a stream weighted member connected to vary the stream by acting upon one of said means.

In witness whereof I hereunto set my hand in the presence of two witnesses.
